Moving Forward In Our Technology World at Vidor High SchoolKay Abernathy: One change I've made in teaching is adding the web conference opportunity for students to meet each other and talk about clarifications they need with their assignments. At LU we use Adobe Connect Pro which is expensive but workable. An open source software for conferencing is dimdim.com. You might want to try it. Let me know if you find other nonexpensive conferencing software.
